Big news, everyone! We have a release date! Drum roll, please......
July 7, 2026
I can’t wait for you to finally meet Anna.
Thanks for staying with me on this journey. It will be worth the wait!
With gratitude,
Sonja
P.S. The kindle edition is already available for pre-order on Amazon. Check it out!
Greetings, Adventurers.
It has been awhile. 11 months to be exact. Which is actually kind of funny, considering we have 11 months until something amazing finally happens.
In 11 months, dear readers, you will finally be holding a copy of Mushroom and Anchovy in your hands. We have a release date, and skeleton listings have started populating on major retailers’ websites. To date, I have seen them on Target, Walmart, and Amazon’s web stores. The cover image will be added over time, as well as further details, but I’m sure it goes without saying that having a release date and preorder links are huge steps forward.
"All right, Kate, GIVE US THE RELEASE DATE ALREADY!" Yes! You’ve waited long enough, so here it is: Mushroom and Anchovy will be officially released on June 2, 2026.
If you are still at the address you used when you preordered, all you have to do is sit back and wait until the book releases next year. Otherwise, please send an e-mail to hello@inkshares.com to update and confirm your current address, along with your order information so the folks behind the scenes can link up the two.
As well, this will be my final book published under the pseudonym of K. M. Cooper. Times and people change, and I will be using the name I’m known for, Kate Butland, with further publications. I am currently in the editing process of another trilogy, and I will update accordingly as that progresses. For now, you can find me regularly over at my Substack, where I am currently migrating my former website in between releasing new writing. My Substack writing is available completely for free, and you can subscribe to receive updates on what I’m working on.
I cannot wait for this book to be in your hands. It looks like I will have to, for another 11 months or so, but I hope that you will enjoy it when the time comes, and I thank you all for your endless kindness, patience, and support during this time. I couldn’t have done it without you.
May your travels be fraught with wonder and just enough peril to keep them interesting,
Kate Butland (K. M. Cooper)

Dear readers,
It has been a long while since my last update, and you must be surprised to hear from me again. My second book, Unnatural Ends (formerly titled Cat’s Paw) was released back in 2023 and should be available through all the usual channels; and now, I’d like to announce the upcoming release of my third book, A Pretender’s Murder, currently set for July 2025 in North America and September 2025 in the UK.
Yes, that’s "upcoming release", not "pre-order campaign". It seems as though A Gentleman’s Murder was successful enough that no pre-order campaign was required for its sequel. So what is this sequel, then? Well ...
It’s the spring of 1925, and Eric Peterkin is settling into his position as the newly installed club secretary of the Britannia Club. Until elections can be held, the acting club president is Colonel Hadrian Russell: charming, magnanimous, immensely popular, a man who began the War with four strapping sons and ended it with four widowed daughters-in-law. But when the Colonel is shot and thrown bodily through one of the front upstairs windows of the club, Eric is called upon once again to investigate. The quest takes him through Paris to an isolated Swiss sanatorium and back, before putting him on a manhunt for an elusive former spy. As it turns out, the intrigues born on the home front are no less deadly for having occurred while the men were miles away.
Does that pique your interest? Then keep an eye out for it! In the meantime, I’ll be over here working on a third mystery for our friend Eric Peterkin ...
